I I'll! mu aII/ INVE TOR BY (7mm ATTOR N EY Patented Dec. 26, 1939 umrreo STATE-5W aren't oFFic-e My invention' relates to" ceiling fan hangers,

particularly to hangers including a buffer device or/and self-staying means. I I

One of'the objects of the invention is *to provide a self-staying fan hanger, to dispensewith' unsightly guy lines and brackets conventionally used to prevent oscillation of a motor fan.

Another" object of the" invention is to provide a buffer fan hanger that will insulate shocks caused by motor action and prevent objectionable noises.

Another object is to provide a hanger easy to make, easy to set up, easyto take down, simple, practical and economical.

These and other objects are attained by means illustrated and described in the following specification, and defined in appended claim.

For the purpose of disclosure, I'show two only. of many forms that may embody the invention. In one of these the fan hanger is mounted on the head of a lag screw set in a joist, beam or thelike, and having its head and a. short part of its body extending below the ceiling. In the other form of the invention, the hanger is connected to a threaded pipe projecting through the ceiling.

Both of the illustrative forms of the invention preferably include a ceiling or wall support-fastener, or means for connecting the hanger to a ceiling'or wall support; a motor fan connector, or means for connecting the hanger to some part or member of a fan or' like motor driven implement; self-staying means and buffer means. These parts thus named for convenient reference, will hereinafter be more fully described.

In the drawing: a

' Referring to Figs. 1, 2 and which show a self-stayed and buffer fan hanger mounted and locked onthe headof alag screw: tlds a ceiling or wall support fastener, ormeans'for connecting'a hanger to. any suitable support, and lll'is a motor fan connector, ormeans. for'connecting a" hanger to the stem orv other; member of.,a fan. II is the head-ofa lagscrew and l2-is its seat onthe hanger: The wall or ceilingplate is freely telescopes the body of the lag screw, washer like, and is provided with a circular concentric retainer ridge l4. These parts cooperate to hold the hanger and lag screw against co-relative rotation and substantially co-axial in the preferred form. Freeways l5 and l 6, re-

spectively for the body and head of the lag screw, facilitate mounting and demounting the hanger. Lock shoulders I! operate to secure the head of the lag screw in place and the longitudinal bore 88 and cross freeway facilitate elec tric wiring. I9 is any suitable buffer means which is preferably enclosed in the housing 20, to insulate shocks and jolts and prevent noises thereby, caused.

In the modified form of the invention, Figs. 4-8, 2| is a stationary member adapted to being mounted on a pipe projecting from the ceiling and to demountably provide a seat or support for the hanger. 22 shows a shoulder or retainer that co-operates with removable keeper 23 to lock the hanger in place. The said keeper may consist of a 'U shaped member having one or both of its terminals threaded and provided with nuts as shown; or the keeper may comprise a single bolt or pair of bolts, such as carriage bolts with heads out to fit thefreeway 24. The latter facilitates seating the head of the support-fastener 25, which in preferred form is a member of hollow rectangular section, with an enlarged base flaring to match the fan-connector 26 to which it is contiguously assembled but separated and adjacently surrounded by any suitable buffer means 2i. erably of metal, may enclose the said bufi'er means and assembled parts. The electric wiring is facilitated by the longitudinal hollow and the cutaway part 29 of the support fastener.

It will be understood that the buffer material or means, although shown as sheet rubber, may comprise rubber orthe like vulcanized in suitable molds, or raw rubber filling the housing and vulcanized in place, or any device including the like of springs arranged to comprise an equivalent bufier hook-up.

Shape and form of the hanger are not essen- The housing 28, preftial, but that shown is now believed to be preferable.

A self-staying hanger may be constructed in one piece, including the support-fastener 9 and the fan-connector II]; or having in one piece said support fastener, fan-connector and ceiling plate l3 all made in one piece, and provided with the longitudinal bore and freeways equivalently as shown; and it may be round or of any other de sired shape.

When sheet rubber is used as the buffer mean it may be convenient to stamp or cut the housing blank to match the buffer sheet blank,then

to fold and crimp both togethenas shown in Fig. 1. l

Mounting a hanger of the form shown in Figs. 1-3, the lag screw should be backed or screwed from its seat to provide about A, inch play between the head of the lag screw and ceiling.

Then, with the body and head of the lag screw lation caused by motor action.

.It will be understood that by reversing th foregoing procedure, the hanger may be easily demounted.

The foregoing forms of the invention, presently believed best, have been selected for-disclosure, with the understanding that the inven v 5 tion is 'not limited to the details shown; for example, the ceiling plate I 3 may be secured in place by a plurality of ordinary screws and provided withmeans equivalent to those shown for demountably supporting, insulating and staying 10 a motor fan.

I claim the following combinations, and combinations to these equivalent:

Means for mounting a ceiling fan compris- 7 ing: afianged headed support adapted to be secured to the ceiling, ,a laterally engageable con-, nectable sleeve adapted to be demountably-held on the head of said support, co-operating means. on said headed support and said sleeve to prevent relative turning therebetween, a fan attach- 2O ing sleeve surrounding said first mentioned other" sleeve, and a sleeve of rubber-like materialim terposed between said two sleeves for connecting them together and acting as a' vibration absorbing means to prevent vibration incident tcthe 25 operation of said fan being transmitted to SEYMOUR J MEs STEWART,
